# Debt avalanche guide — highest APR first

Clone buyer-channel shape: [aissam_baidi/46bl Free Debt Avalanche Google Sheets Template (2026)](https://dev.to/aissam_baidi_2934207fc2c3/free-debt-avalanche-google-sheets-template-2026-46bl).

## Why avalanche

The debt avalanche orders accounts **highest APR first**. You pay minimums on everything, then throw all extra cash at the highest-rate balance until it clears. When that card hits zero, roll its payment into the next-highest APR.

Avalanche mathematically minimizes total interest. On realistic 3–6 card scenarios with mixed APRs, savings versus snowball are often **$150–$700** — sometimes more when APR spreads exceed 10 percentage points.

The tradeoff: the first payoff is often slower than snowball because the highest-APR card is rarely the smallest balance. Completion rates run slightly lower per Kellogg research. Use avalanche when discipline is strong and APRs differ meaningfully.

## How it works in this tracker

1. List every debt in `debts-template.csv` with balance, APR, and minimum payment.
2. Add any extra monthly payment pool (applied to the highest-APR card first).
3. Run the CLI — debts sort highest-APR-first automatically.
4. When a card clears, roll its payment into the next-highest APR.
